sole at the heel portion of the shoe. VThis heel seat memberis sometimes in the nature of a full lift and sometimes it is cut out at the center thus giving it a sort of horseshoe shape. The front edge of this heel seat member* is usually skived to overlap the skived ends of the welt, this heel seat member being attached to the heel portion `of the inner sole by means of nails, tacks or similar fastening devices.

lVhen the rubber outer sole is applied it is bodying` my invention, parts being broken out sewed to the welt around the fore part of the shoe as usual in welt Vshoes and the heel portion of the outer sole is cemented, nailed or otherwise fastened tothe heel seat member.

It is the object of my present invention to provide a novel shoe having a rubber sole which does not necessitate the use of the separate heel seat member above referred to and which hasheretofore been commonly used. In securing this end I propose to incorporate a layer of relatively stiif unyielding material, such as leather, fibre or similar material in the heel portion of the outer sole, such layer taking the place of the heel seat member heretofore employed and furnishing an anchorage by which the heel portion of the outer sole can be nailed or fastened to the inner sole. v

This layer can be incorporated in the outer sole by placing it in the mold in which the rubber sole is formed sothat said layer becomes vulcanized to the rubber material of the sole. This layer will preferably be located on the upper or inner side of the outer Sole at the heel portion and will thus rest directly against the heelportion of the inner l Vout .departing in any way from the invention. As shownin the drawings lthe layer is about sole. v

A shoe embodying my invention is equally as good asone made according to the former practice with the heel seat member and it can be made less eXpensively since the operar tion o f building ,the heel seat memberv into the shoey is omitted. t Y In order to give an understandin'gof the invention I have illustrated inthe drawings a yselected embodiment vthereof which will now be described after which th'eno'vel fea@ tures willbe pointed .out in the appended claim.

Eig. l is a perspectiveview of an outer rubber sole for a-"shoe embodying vmy invention;

F ig. 2 is a perspective View of the layer of relatively. stiff material which is incorporated in the outer sole; t

Fig. 3 is a fragmentary view of a shoeemto better shown the construction.

The drawings illustrate ,theinvention as it would be applied .to `a welt shoe having'a rubber outer .solev and inthe drawings lfin'- dicates a portion of a welt shoe which is proff vided' with the usualV upper 2, insole Band welt 4;. The outer sole is indicated at 5 and this is of rubber or ,somerubben composition -and is .sewed to thewelt'ilby the stitches 6 as .usual in the manufacture of welt Shoes.

The heel portioniof the outer sole' has in'- Acorporated therein a layer 7 of fibre,`le'ather or; some other relatively stiff material. `This layer 7 is preferably located on the upper or inner side ofthe outer sole. In making the outer sole with the layer 7 incorporated thereinI propose to ,place this layer inthe mold .in which thesoleV is made .so that during the formation of thesole the rubber will be :molded to the' layer 7. In" the manufacture of theserubberfsoles therubber is subjected to'a. vulcanizingy action while in the mold Vand during this operation the layer 7 becomes vulcanized to the rubber of the insole.`

The thickness of the layer 7 may vary withhalf the thickness of the outer sole so that the rubber part of the outer sole at the heel portion thereof, Which is indicated at 8, is only about half the thickness of the main body of the sole` The relative thickness of the rubber and fibre or leather portion of the insole may be varied, however, Without departing from the invention. When the sole is completed it constitutes a unitary device With the layer 7 incorporated in the sole as an integral part Y thereof.

In the manufacture of the shoe embodying my invention the upper Will be lasted to the insole and the Welt l seWed thereto in .usual through said layer of relatively stiff material and the inner sole to fasten the inner sole and outer sole together at the heel portion, and the heads of said tacks being anchored against the bottom face of said layer of relatively stiff material and being concealed by the rubber layer.

In testimony whereof, I have signed my name to this specification.

Way. After this is done the bottom of the t shoe is prepared for the reception of the rubber sole and the rubber sole is also applied to the shoe bottom and is seWed to the Welt 4 by the stitches 6 all as usual. Vhen the outer sole is placed in position the layer 7 of relatively stiif material will lie directly against the heel portion of the insole 3 and Without the interposition of the heel seat member that has been usually employed.

If desired, the heel portion of the outer sole may be secured to the heel portion of the inner sole by means of suitable fasteners 9, the layer 7 constituting a firm anchorage for such fasteners.

The rear end 10 of thev Welt is shown as skived orbevelled and the front edge l1 of thelayer 7 is also shown as bevelled, although the latter is not an essential feature of the invention.

By means of this invention it is possible to build a Welt shoe With a rubber sole in the same manner employed in building a Welt shoe With a leather sole. When the leather sole is used it is applied directly to the bottom of the lasted shoe Without the interposition of a heel seat member, the heel portion of the leather sole lying rdirectly against the heel portion of the inner sole. By employing the stiilening layer 7 in the rubber outsole it is possible to use the same method in attaching the rubber outsole to a shoe of the Welt type, the layer 7 taking the place of the usual heel seat member which has heretofore been used when the shoe is made With a leather outsole.

l2 indicates a rubber heel which is secured to the shoe in usual Way, that is, by being cemented thereto as Well as by means of suitable fastenings 13.

IV claim:

A shoe comprising an insole, an upper, a rubber outsole extending the full length of the shoe, the heel portion of the outsole having incorporated therein but exposed on its inner or attaching face a non-perforated layer of material which is inherently relatively stift', whereby the heel portion of the sole comprises an outer layer of rubber and an inner layer of the relatively stiftl material, said layer of stili material lying `directly against the heel portion of the insole, and tacks extending
